Ancestral Method

Slow processes,
as nature commands.

It is not just flour. It is the result of forty days of smoke, the heartbeat of a water mill and the silence of the Apennine woods.

Phase One

From the forest to the metato

The metato is a small two-storey stone structure. Here the chestnuts are spread on a wooden grid while a slow fire of chestnut wood and husks burns on the ground floor.

Forty days of patience. The smoke envelops every nut, drying it slowly without cooking it. It is an alchemy of constant heat and aromatic smoke that gives the flour that lightly toasted aftertaste, unique of its kind.

The ritual of fire

"The flame must never touch the grid. It is the warmth of the forest's soul that transforms the fruit."

Phase Two

Optical sorting

Between drying and milling, every chestnut passes through a technologically advanced optical sorter. High-resolution cameras and analysis algorithms reject in real time every defective, dark, worm-eaten or imperfectly dried nut.

It is where farming tradition meets technology: the ancient know-how of the metato, and the digital eye that guarantees only the best chestnuts to those who buy. No surprises in the bag — only the best of the harvest.

Guaranteed cold milling to preserve enzymes.

Phase Three

The stone mill

After optical sorting, the chestnuts are taken to the mill. The great French stones, restored by hand, turn slowly as tradition demands.

Unlike industrial mills, the stone does not heat the flour. The grain stays irregular, "alive", carrying all the oils and aromas that mechanical heat would destroy.

The restoration

Since 2022, inside an old cowshed.

The mill is not new: it has returned. Work began in 2022 inside a former cowshed, forgotten for decades. We recovered and hand-chiselled stones from the 19th century, rebuilt walls, redone the milling-floor structure.

Today it runs at 100 revolutions per minute — slowly, as it should. It doesn't heat the flour, doesn't destroy the chestnut's essential oils, giving back a living product that industrial mills cannot make.
